COMBINED LADDER AND HOSE-NOZZLE-CONTROLLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 703,115, dated June 24, 1902.

Application filed February 3, 1902. Serial No. 92,405. No model.)

To all whom, it may concern.-

Be it known that we, JOHN 000K and AXEL Gr. ENGWALL, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Combined Ladder and Hose-Nozzle-Oontrolling Apparatus, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description, sufficient to enable those skilled in the art to which it pertains to understand, make, and use the same.

This invention relates to a combined ladder and hose-nozzle-controllin g apparatus for use at fires, such ladders being usually mounted on trucks on which they may be rapidlyhauled to conflagrations where the same are to be used and such ladders also usually consisting of more than one section and provided with means for erecting or partially erecting the same; and the object of this invention is to obtain a combined ladder and hose-nozzle-controlling apparatus which will not interfere with the erection or partial erection of the ladder and by means of which the nozzle of a firemans hose can be controlled by a person standing at the base of the ladder and water flowing from such nozzle may be delivered in any desired direction.

In the drawings referred to as forming a part of this specification, Figure 1 is a side elevation of the upper end of a ladder combined with a fire-hose-nozzle holder embodying the principal part of this invention. Fig. 2 is a section view on line 2 2 of Fig. 1 viewed in the direction indicated by the arrows, with the hose-nozzle shown in Fig. 1 removed from such holder. Fig. 3 is an elevation of a short section of the upper end of a ladder combined with the hose-nozzle holder shown in Figs. 1 and 2. Fig. 4 is a side elevation of the bottom of a short section at the lower end of a ladder with drums and a crank, forming a part of the apparatus embodying this invention; and Fig. 5 is a sectional view on line 5 of Fig. 4 viewed in the direction indicated by the arrows.

A reference-letter applied to designate a given part is used to indicate such part throughout the several figures of the drawings wherever the same appears.

A is the upper end of a ladder.

B is the ordinary extension of the upper end of the side rails of the upper section of a firemans ladder and comprises a strap-iron part which is secured to the side rails "of the ladder, as by bolts 1).

O O are rungs.

D is a standard which is secured in place in the extension 13, as by bolts d d.

E is a crank-rung bent or built up to form a double crank and constitutes a llOZZlG", holder mounted in standards D D. The holder E consists of the movable double crank part c, the strap 6, pivoted to part e, as by pivot 6 and the lever E, rigidly secured on part 6. By means of lever E and cables H H the hose-nozzle holder E is turned or rocked in the standard D D. The part 6 and the strap e of the hose-nozzle holder E are respectively provided with apertures e a in which apertures the ordinary Wrench or spanner engaging pin f of the hose-nozzle F fits when the hose-nozzle is placed in the nozzle-holder and strap 2 is closed onto such nozzle, as is illustrated in Figs. 1 and 3 of the drawings.

(2 is a projection on part c of nozzle-holder E. Strap e is provided with aperture a,

through which aperture projection e extends and in which aperture it is firmly held, as by pin c", Fig. 3, to maintain the strap e closed onto the nozzle F.

G is the hose of nozzle F.

The ropes, cords, or cables H H respectively extend from lever E to near the ground, and preferably they extend to and around the drums I I.

' J is a short section of the lower end of aladder. Ladder A, herein before described, may constitute an extension end or a section to the ladder J.

K is a shaft rotatably mounted in one of the side rails of ladder J, and 7c is the crank of such shaft K. The drum I is rigidly attached to shaft K to rotate therewith, while the drum 1 is loosely mounted on such shaft K to turn freely thereon.

L is a disk loosely mounted on shaft K between the adjacent ends of the drums II, so as to turn freely on the shaft.

M M M are gear-wheels which are respectively rotatably mounted in disk L, so that the teeth of such gear-wheels project or extend beyond the faces of the disk, and the adjacent ends of the drums I I are provided with gearteeth intermeshing with the teeth of such gear-wheels M M 'M. The gear-teeth on the end of the drum I, which intermesh with the gear of wheels M H M, are indicated by broken lines N N in Fig. 5. v

O is a pin fitting into the projection P in the edge of the disk L. When the pin 0 is fitted into such projection P, the outer end of the pin comes in contact with side railj of lad der J, thereby preventing the disk L from turning. At such time when crank K and drum I are turned in one direction by means of the crank the remaining drum 1 is turned in the other direction by the interposed gear-teeth M M M between the drums, and thereby as the rope H is wound on or unwound from drum I the rope II will be un wound from or wound onto the drum I a corresponding amount. When the pin 0 is taken from the projection P, disk L may turn freely on shaft K, and the drums I I may turn freely relative to each other. The pin 0 is thus removed while the ladder A is being extended on'ladder J. When the ladders A J have been adjusted relative to each other, the pin 0 is inserted in projection P to prevent rotation of disk L, and the crank his turned until the nozzle F is in position to direct the water flowing therefrom in the direction desired.

When the ladder is to be used without the hose-nozzle F being attached to the nozzleholder E, the pin 6 is withdrawn from proj ection e, and the strap 6 is thrown back from the part c of the nozzle-holder and the nozzle taken therefrom. When the nozzle F is contained in the nozzle-holder E, as illustrated in Figs. 1 and 3 of the drawings and hereinbeiore described, with the spanner-pins ffof the nozzle in the apertures e 6 such nozzle is maintained firmly in position and may be turned, by means of the ropes or cables H H, to direct Water in a desired direction and from a position so close to fire or smoke that a fireman or other person would be unable to stand and maintain such nozzle in such position.

Having thus described the invention, what we claim, and desire to secure by Letters Patent, is-
